The editing of the ambush scene in this film in which Bonnie and Clyde are killed has been very influential, and Allen credited Greenberg with its actual "cutting".
A native of New York, as a youth, Greenberg learned to edit music and began familiarizing himself with the moviola, splicers, synchronizers and recorders.
[1] Greenberg edited two films with director William Friedkin, The Boys in the Band (1970) and The French Connection (1971).
In 2012, The French Connection was selected as the tenth best edited film of all time in a listing compiled by the Motion Picture Editors Guild.
[14] In the 2012 critics' poll conducted by the British Sight & Sound magazine, Apocalypse Now was rated the fourteenth best film ever made.
But De Palma began gaining respectability with Dressed to Kill (1980) and following several critical setbacks, reached the apex in the late 80s with such high-powered productions as The Untouchables (1987) and Casualties of War (1989).
Greenberg has been elected to membership in the American Cinema Editors,[17] and in 2015 that organization honored him with its Career Achievement Award.
[3] Writing after the ceremony at which Greenberg received the Career Achievement Ward, Ross Lincoln and Erik Pedersen said, "if editing is the most important part of completing a film, he is one of the most quantifiably influential people in the past 40 years.
"[18] On the 2012 list of "best edited films of all time", Greenberg worked on three of the top ten: Bonnie and Clyde, The French Connection, and Apocalypse Now.
[11] Greenberg died on December 22, 2017, at the age of 81 This filmography of feature films is based on the listing at the Internet Movie Database.
